Review | We Test The Carbon Specialized Stumpjumper EVO Pro 27.5

by 6

In case you hadn’t heard already, Specialized has just announced the Carbon Specialized Stumpjumper EVO Pro 27.5. You can get all the details of the bike right here, though read on for our first ride review from local Calder Valley tester, Nick Cummins. Over to Nick for the review.


If like me, you’re a mountain bike nerd, the release of a new Stumpjumper is always something to look forward to. While some complain that it is the Ford Mondeo of the mountain bike world, there always seems to be an interesting model tucked away – an RS fire breathing monster with the daft whale tail.

This time we were in for a real surprise.

Released in aluminum only, the Stumpjumper EVO leapt out from the lineup; low slung, stretched out and looking very proto, it caught everyone’s attention. I remember Wil testing it on a press outing in Spain and finding it “vaguely terrifying”. All very unlike Specialized.

So stealth, you have to shout ‘I’m here’ when you cross the finish line.
Doesn’t really count as a splash of colour.

There have been previous iterations of the EVO name attached to various Specialized bikes in the past, and there’s an Epic EVO available to buy now, but none have ever been as extreme as this bike. After some very favourable reviews of the metal version, here then, offered for test is the bike that no one will be surprised has been released: The carbon version of the Stumpy EVO.

The Bike

Where the original was all brushed bare metal “proto/race” looking test rig, this semi satin finished carbon version looks the opposite; much more the finished article. All black component choices making it look stealthy. Very much Batman’s Mountain bike.

Matt black, done well.
The carbon finish only really shows up in the brightest of light.

It can be a tough look to pull off well, all black bikes sometimes can look, let’s be honest, a bit cheap, but Specialized has managed it. The silhouette of the bike helps to give the whole thing a purposeful stance.

A closer look at the component choices shout rather than hint at the bike’s intended purpose. There’s a 150mm travel Fox 36 Performance Elite fork out front, which gear snobs may point out hasn’t the benefit of Kashima coated stanchions. But once pressurised and set up, it performed faultlessly in test, only being slightly outshone by the Fox DHX2 coil shock out the back.

Black boing.
Kashima coating would be wrong!

Code RSC brakes with 200mm rotors all round, made for brutally efficient braking with all the adjustment you could possibly need. Even on my steep trails, in the dry I found I could happily control my speed with the just the rear brake, almost bringing the bike to a complete stop on one occasion in order to regain my balance to make a particularly sharp stepped turn. Top stoppers then. Be warned though when the weather turns wet they do like to sing…

The drivetrain is exclusively GX and although from the more moderately priced end of SRAM’s Eagle family still offers wide range, snappy changes. Climbing feels almost like cheating in the big 50t rear.

Spanky in the car park, great on the trail.
SRAM takes care of the drivetrain.
SRAM stoppers too.

The seat post is Specialized’s new Command dropper, which in car park tests rises with wince-inducing haste. In use, however, its light action means that it’s easy to control with your legs and body weight, so I’m happy to report, no soft parts were harmed during the testing of the EVO.

Specialized’s own Butcher GRID 2.6in trail tyres around Roval carbon rims made for an interesting combo. Boost hubs, on 27.5in carbon rims with a stiff fork, meant that the front of this bike will go exactly where it’s pointed – something that the Butcher Grid tyre on the front at least sometimes found difficult to cooperate with. The end result was often a bit “Tight, but loose” as our surfing cousins would say. Especially in the wet, it wasn’t particularly confidence inspiring.

These were a little interesting in the wet.

The frame has internal cable routing, with the SWAT box and bottle cage all present and correct. These I’ve found will happily swallow everything from spare inner tubes and pumps to food, and even a gilet on one occasion. Combined with the SWAT tool hidden in the stem (and released by a very smoothly swinging top cap and pleasing pop up action) which includes a chain tool and spare chain link holder, means that you can easily have an evening’s blast unencumbered by a backpack if you so chose.

Specialized’s own brand saddle and grips round off what I thought were well-chosen components. All this combined with a super slack 63.5° head angle, 450mm reach in this – the S2 size – and low bottom bracket height tick all the right “on point marketing segment” boxes.

So, has Specialized managed then, to put together a bike that actually rides as well as the specs sheet suggests? I was eager to find out.

*Magazine features are articles reproduced from published issues of Singletrack magazine.

Why do you ask for registration to view some articles?

We get asked this a lot. The simple reason is that content is increasingly expensive to commission, create and publish and where once the cost of this process was mostly covered by advertising revenues, now that’s no longer the case. We increasingly rely on our paying members to keep Singletrack going and we’d love you to become one of our supporters. however, that’s not we are asking right now. You can read the rest of this feature simply by registering an account on our site.

How does being a free, registered user help you?

A good question and it’s a bit complicated. It’s NOT so we can sell your email details, or even to send you newsletters. Our last newsletter was sent out in early 2018 – we really should send out a few. It’s not so we can show you more ads either – in fact when you register we show you fewer ads. The reason is actually because registered users come back and look at more of our content. They start interacting with us and posting comments of their own and joining in forum discussion. That level of interaction is what eventually feeds our new subscriber numbers and so for us the journey to gaining new subscribers is to start by encouraging you to simply register an account. We hope that the benefits that will bring to you will be the first step in you joining us as a paying Singletrack Premier supporter.

    I have the standard 27.5 LT and flipping love it. This must be a barrel of laughs pretty much anywhere.

    Wouldn’t going for the S3 only exacerbate your issue with front end grip?
    It would push distribution of weight (primarily coming through the pedals) further towards the rear wheel, unloading the front even more.

    Can’t decide between 27.5 and 29. The bike looks flipping awesome

    The S2 has 465mm reach in low setting, not 450mm. That should be plenty room for 178cm rider, at least when standing,..

    I’ve got an S3 and it’s everything that was said and more. The frame is beautiful, it’s super quiet and the most capable bike I have ridden.
